Detailed Description

<<extension>> QoS libraries, profiles, and snippets that are automatically built into RTI Connext.

The built-in profiles can be accessed in QoS XML configuration files and by using any of the APIs that accept library and profiles names by using the constants or string versions as documented on this page.

The built-in profiles are provided as a way to quickly and easily configure RTI Connext applications with a set of QoS values aimed at achieving a specific behavior.

There are three built-in QoS libraries:

There are three types of profiles:

There are several types of QoS Snippets. These are the current QoS Snippets available:

These QoS Profiles can be used as base profiles in XML configuration, then QoS Snippets can modify specific aspects of this base QoS Profile, and finally files and values can be modified to fit a specific system's needs. For example:

<qos_profile name="MyProfile" base_name="BuiltinQosLib::Generic.Common">
<domain_participant_qos base_name="BuiltinQosLib::Generic.Monitoring.Common">
<base_name>
<element>BuiltinQosSnippetLib::Feature.Monitoring.Enable</element>
</base_name>
<!-- Override and add values -->
</domain_participant_qos>
</qos_profile>

The QoS Profiles can also be used in any APIs that call for a QoS library and profile name, for example, the create_*_with_profile() APIs. To create a DDSDataWriter configured to send large data:

writer = DDS_DomainParticipant_create_datawriter_with_profile(
participant, topic,
const char *const DDS_PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA_FAST_FLOW
Configures strictly reliable communication for large data with a fast flow controller.
const char *const DDS_BUILTIN_QOS_LIB
A library of non-experimental QoS profiles.
#define DDS_STATUS_MASK_NONE
No bits are set.
Definition: infrastructure.ifc:1425

All the built-in QoS Profiles and QoS Snippets are documented in the BaselineRoot.documentationONLY.xml and BuiltinProfiles.documentationONLY.xml files that are included in the NDDSHOME/xml directory of the RTI Connext installation.

◆ DDS_PROFILE_GENERIC_MONITORING_COMMON

const char* const DDS_PROFILE_GENERIC_MONITORING_COMMON
extern

Enables RTI Monitoring Library.

Generic Base participant QoS Profile that enables RTI Monitoring Library.

Use of this QoS Profile is deprecated. It is included for backwards compatibility.

Instead of using the (deprecated) "BuiltinQosLib::Generic.Monitoring.Common", apply the QoS Snippet "BuiltinQosSnippetLib::Feature.Monitoring.Enable" via composition. For example:

<qos_profile name="MyProfile">
<base_name>
<element>BuiltinQosSnippetLib::Feature.Monitoring.Enable</element>
</base_name>
</qos_profile>

Legacy applications may use this QoS Profile via inheritance. To do this, create a derived QoS Profile that inherits from this one. For example:

<qos_profile name="MyProfile" base_name="BuiltinQosLib::Generic.StrictReliable">
<domain_participant_qos base_name="BuiltinQosLib::Generic.Monitoring.Common">
</qos_profile>

String-version: "Generic.Monitoring.Common"

◆ DDS_PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY

const char* const DDS_PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY
extern

Sets the values necessary to communicate with RTI Connext Micro.

This profile will always represent the QoS values required for interoperability between the most recent version of RTI Connext Micro at the time of release of the most recent version of RTI Connext.

In Library: DDS_BUILTIN_QOS_LIB

String-version: "Generic.ConnextMicroCompatibility"

◆ DDS_PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY_2_4_9

const char* const DDS_PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY_2_4_9
extern

Sets the values necessary to communicate with RTI Connext Micro versions 2.4.4 through at least 2.4.9.

At the time of the release of RTI Connext 5.3.0 it was not necessary to set any QoS values in order to interoperate with RTI Connext Micro. This applies to RTI Connext Micro versions 2.4.4 and later. The most recent version of RTI Connext Micro at the time of release of RTI Connext 5.3.0 was 2.4.9. There is no guarantee that this profile will interoperate with versions of RTI Connext Micro after 2.4.9.

In Library: DDS_BUILTIN_QOS_LIB

String-version: "Generic.ConnextMicroCompatibility.2.4.9"

◆ DDS_PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY_2_4_3

const char* const DDS_PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY_2_4_3
extern

Sets the values necessary to communicate with RTI Connext Micro versions 2.4.3 and ealier.

RTI Connext Micro versions 2.4.3 and earlier only supported the DDS_MANUAL_BY_TOPIC_LIVELINESS_QOS LivelinessQos kind. In order to be compatible with these versions of RTI Connext Micro, the DDSDataReader and DDSDataWriter must have their Liveliness kind changed to this value because the default kind in RTI Connext is DDS_AUTOMATIC_LIVELINESS_QOS.

In Library: DDS_BUILTIN_QOS_LIB

String-version: "Generic.ConnextMicroCompatibility.2.4.3"

◆ DDS_PROFILE_GENERIC_OTHER_DDS_VENDOR_COMPATIBILITY

In Library: DDS_BUILTIN_QOS_LIB

String-version: "Generic.OtherDDSVendorCompatibility"

◆ DDS_PROFILE_GENERIC_510_TRANSPORT_COMPATIBILITY

const char* const DDS_PROFILE_GENERIC_510_TRANSPORT_COMPATIBILITY
extern

Sets the values necessary to interoperate with RTI Connext 5.1.0 using the UDPv6 and/or SHMEM transports.

In Library: DDS_BUILTIN_QOS_LIB

String-version: "Generic.510TransportCompatibility"

◆ DDS_BUILTIN_QOS_LIB_EXP

const char* const DDS_BUILTIN_QOS_LIB_EXP
extern

A library of experimental QoS profiles.

Experimental profiles are new profiles that have been tested internally but have not gone through an extensive validation period. Therefore some of the settings may change in future releases based on customer and internal feedback. After validation, experimental profiles will be moved into the non-experimental library.

QoS Profiles in this library are deprecated. They have been moved to "BuiltinQosLib". You should use the QoS Profiles from "BuiltinQosLib" instead of the ones in "BuiltinQosLibExp". The experimental profiles are still defined here to avoid backward compatibility issues.

String-version: "BuiltinQosLibExp"

◆ DDS_PROFILE_GENERIC_STRICT_RELIABLE

const char* const DDS_PROFILE_GENERIC_STRICT_RELIABLE
extern

Enables strict reliability.

Configures communication to be "strict reliable" where every sample is reliably delivered.

Combines the use of the DDS_RELIABLE_RELIABILITY_QOS for DDS_ReliabilityQosPolicy with a DDS_KEEP_ALL_HISTORY_QOS for the DDS_HistoryQosPolicyKind.

This QoS Profile also optimizes the reliability protocol setting for this configuration.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.StrictReliable"

◆ DDS_PROFILE_GENERIC_KEEP_LAST_RELIABLE

const char* const DDS_PROFILE_GENERIC_KEEP_LAST_RELIABLE
extern

Enables keep-last reliability.

Like the Generic.StrictReliable profile, this profile ensures in-order delivery of samples. However, new data can overwrite data that has not yet been acknowledged by the reader, therefore causing possible sample loss.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.KeepLastReliable"

◆ DDS_PROFILE_GENERIC_BEST_EFFORT

const char* const DDS_PROFILE_GENERIC_BEST_EFFORT
extern

Enables best-effort reliability kind.

This profile enables best-effort communication. No effort or resources are spent to track whether or not sent samples are received. Minimal resources are used. This is the most deterministic method of sending data since there is no indeterministic delay that can be introduced by resending data. Data samples may be lost. This setting is good for periodic data.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.BestEffort"

◆ DDS_PROFILE_GENERIC_STRICT_RELIABLE_HIGH_THROUGHPUT

const char* const DDS_PROFILE_GENERIC_STRICT_RELIABLE_HIGH_THROUGHPUT
extern

A profile that can be used to achieve high throughput.

This QoS Profile extends the DDS_PROFILE_GENERIC_STRICT_RELIABLE QoS Profile to perform additional, fine-grained performance tuning specific to applications that send continuously streaming data. The parameters specified here add to and/or override the parameters specified in the DDS_PROFILE_GENERIC_STRICT_RELIABLE QoS Profile..

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.StrictReliable.HighThroughput"

◆ DDS_PROFILE_GENERIC_STRICT_RELIABLE_LOW_LATENCY

const char* const DDS_PROFILE_GENERIC_STRICT_RELIABLE_LOW_LATENCY
extern

A profile that can be used to achieve low latency.

This QoS Profile extends the DDS_PROFILE_GENERIC_STRICT_RELIABLE QoS Profile to perform additional, fine-grained performance tuning specific to applications that send continuously streaming data. The parameters specified here add to and/or override the parameters specified in the DDS_PROFILE_GENERIC_STRICT_RELIABLE QoS Profile.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.StrictReliable.LowLatency"

◆ DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA

const char* const DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA
extern

A common Participant base profile to facilitate sending large data.

This is a common Participant base QoS Profile that configures 3 different flow controllers: 838, 209, and 52 Mbps that can each be used to throttle application data flow at different rates.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.Participant.LargeData"

◆ DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA_MONITORING

const char* const DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA_MONITORING
extern

Configures Participants for large data and monitoring.

This is a common base Participant QoS Profile to configure Participants to both handle large data and use RTI Monitoring Library.

This QoS Profile is deprecated. It is included for backwards compatibility.

It is recommended that instead of inheriting from this QoS Profile, new applications apply the following QoS Snippets to their application-specific QoS Profiles:

Enable Monitoring

Enable Large Data + optimizations

String-version: "Generic.Participant.LargeData.Monitoring"

DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA
DDS_PROFILE_GENERIC_MONITORING_COMMON

◆ DDS_PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA

const char* const DDS_PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA
extern

Configures endpoints for sending large data with strict reliability.

This QoS Profile extends the DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA QoS Profile to handle sending large samples. This QoS Profile optimizes memory usage per sample within RTI Connext, but it does not do any flow control. You can use this QoS Profile directly, which enables asynchronous publication with the default flow controller (i.e. no flow control) or you can use one of the three QoS Profiles below (Generic.StrictReliable.LargeData.*Flow), which uses this QoS Profile as a common base QoS Profile. Each of these three QoS Profiles uses one of the three flow controllers defined in DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA in order to throttle application data flow.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.StrictReliable.LargeData"

◆ DDS_PROFILE_GENERIC_KEEP_LAST_RELIABLE_LARGE_DATA

const char* const DDS_PROFILE_GENERIC_KEEP_LAST_RELIABLE_LARGE_DATA
extern

Configures endpoints for sending large data with keep-last reliability.

This QoS Profile is similar to the DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA QoS Profile, but also adds QoS Snippets to handle sending large data. You can use this QoS Profile directly, which enables the default flow controller (i.e., no flow control) or you can choose one of the three QoS Profiles below (Generic.KeepLastReliable.LargeData.*Flow) which uses this QoS Profile as a common base QoS Profile. Each of these three QoS Profiles uses one of the three flow controllers defined in DDS_PROFILE_GENERIC_PARTICIPANT_LARGE_DATA in order to throttle application data flow.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Generic.KeepLastReliable.LargeData"

◆ DDS_PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA_FAST_FLOW

const char* const DDS_PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA_FAST_FLOW
extern

<qos_profile name="MyProfile">
<base_name>
<element>BuiltinQosSnippetLib::Feature.Security.Enable</element>

The following DataWriter and DataReader QoS policies of this profile cannot be modified and they are overwritten by the RTI Monitoring Library 2.0:

  • Reliability Kind.
  • Durability Kind.
  • History Kind.
  • Publish Mode Kind.
  • Protocol -> RTPS Reliable Writer -> Max Heartbeat Retries.

This profile uses Topic Filters to select the DataWriter and DataReader QoS depending on the Observability Distribution Topic.

◆ DDS_PROFILE_PATTERN_PERIODIC_DATA

const char* const DDS_PROFILE_PATTERN_PERIODIC_DATA

◆ DDS_PROFILE_PATTERN_STREAMING

const char* const DDS_PROFILE_PATTERN_STREAMING
extern

Used for applications that stream data.

The data sent in streaming applications is commonly periodic. Therefore this profile simply inherits from the DDS_PROFILE_PATTERN_PERIODIC_DATA profile. Note: With this QoS Profile, the application may lose data, which may be acceptable in use cases such as video conferencing.

◆ DDS_PROFILE_PATTERN_RELIABLE_STREAMING

const char* const DDS_PROFILE_PATTERN_RELIABLE_STREAMING
extern

Used for applications that stream data and require reliable communication.

Sometimes streaming applications require reliable communication while still tolerating some data loss. In this case, we inherit from the DDS_PROFILE_GENERIC_KEEP_LAST_RELIABLE QoS Profile and the following QoS Snippets:

This QoS Snippet also increases the DDS_HistoryQosPolicy::depth to reduce the probability of losing samples.

◆ DDS_PROFILE_PATTERN_EVENT

const char* const DDS_PROFILE_PATTERN_EVENT
extern

Used for applications that handle events.

This QoS Profile can be used by applications in which samples represent events such as button pushes or alerts. When events are triggered, the system should almost always do something, meaning that you don't want the system to lose the event. This means that the system requires strictly reliable communication. To enable it, use the following QoS Snippets:

Since events and alerts are critical and non-periodic data, it is important to detect situations in which communication between a DDSDataWriter and DDSDataReader is broken. This is why this profile sets the DDS_LivelinessQosPolicy. If the DDSDataWriter does not assert its liveliness in a timely manner, the DDSDataReader will report 'loss of liveliness' to the application.

String-version: "Pattern.Event"

◆ DDS_PROFILE_PATTERN_ALARM_EVENT

const char* const DDS_PROFILE_PATTERN_ALARM_EVENT
extern

Used for applications that handle alarm events.

An alarm is a type of event; therefore this profile simply inherits from DDS_PROFILE_PATTERN_EVENT.

In Library: DDS_BUILTIN_QOS_LIB and DDS_BUILTIN_QOS_LIB_EXP

String-version: "Pattern.AlarmEvent"

◆ DDS_PROFILE_PATTERN_STATUS

const char* const DDS_PROFILE_PATTERN_STATUS
extern

Used for applications whose samples represent statuses.

This QoS Profile can be used by applications in which samples represent state variables whose values remain valid as long as they don't explicitly change. State variables typically do not change periodically. State variables and their values should also be available to applications that appear after the value originally changed because it is unreasonable to have to wait until the next change of state, which may be indeterminate.

Whether to use this QoS Profile or DDS_PROFILE_PATTERN_PERIODIC_DATA can often be an application choice. For example, if a DataWriter is publishing temperature sensor data, it could use the DDS_PROFILE_PATTERN_PERIODIC_DATA QoS Profile and publish the data at a fixed rate or it could use the DDS_PROFILE_PATTERN_STATUS QoS Profile and only publish the temperature when it changes more than 1 degree.

String-version: "Pattern.Status"

◆ DDS_PROFILE_PATTERN_ALARM_STATUS

const char* const DDS_PROFILE_PATTERN_ALARM_STATUS

◆ DDS_PROFILE_PATTERN_LAST_VALUE_CACHE

const char* const DDS_PROFILE_PATTERN_LAST_VALUE_CACHE
extern

Used for applications that only need the last published value.

With this QoS Profile, a DDSDataWriter will keep in its queue the last value that was published for each sample instance. Late-joining DataReaders will get that value when they join the system. This QoS Profile inherits from DDS_PROFILE_GENERIC_KEEP_LAST_RELIABLE_TRANSIENT_LOCAL because the use case requires delivery to late-joiners.

const char* const DDS_SNIPPET_OPTIMIZATION_DATACACHE_LARGE_DATA_DYNAMICMEMALLOC
extern

Configures the DataWriter and DataReader caches to use dynamic memory allocation for Large Data samples.

Modified QoS Parameters:

This configuration is needed to handle data that contains unbounded sequences or strings. This QoS Snippet is also recommended if samples can have very different sizes and the bigger samples can be very large.

If dynamic memory allocation is not used for the larger samples, then all samples are allocated to their maximum size which can consume a lot of resources.

◆ DDS_SNIPPET_QOS_POLICY_RELIABILITY_RELIABLE

const char* const DDS_SNIPPET_QOS_POLICY_RELIABILITY_RELIABLE
extern

QoS Snippet that sets RELIABILITY QoS to RELIABLE.

This also configures a blocking time in case the DDSDataWriter writes faster than the DataReaders can accommodate.

Modified QoS Parameters:

Note that by itself enabling reliability does not ensure that every sample written is delivered to the DataReaders. This is because the DDSDataWriter and/or DDSDataReader can be configured to override samples in its cache based on the configuration of the DDS_HistoryQosPolicy QoS policy.

To ensure delivery of every sample (at the expense of potentially blocking the DDSDataWriter), use the QoS Profile DDS_PROFILE_GENERIC_STRICT_RELIABLE or one of the derived QoS Profiles.

extern

QoS Snippet that sets RELIABILITY QoS to BEST_EFFORT.

Modified QoS Parameters:

With best-effort, there are no resources spent to confirm delivery of samples nor repairs of any samples that may be lost.

Best-effort communication reduces jitter; therefore, the delay between sending data and receiving it is more deterministic for the samples that are actually received. Best-effort is good for periodic data where it may be better to get the next value than to wait for the previous one to be repaired.

const char* const DDS_SNIPPET_FEATURE_AUTO_TUNING_ENABLE
extern

QoS Snippet that enables auto_throttle and turbo_mode to true.

Sets the DDS_DomainParticipantQos properties to enable auto_throttle and turbo_mode to true.

Modified QoS Parameters:

The domain_participant.auto_throttle configures the DDSDomainParticipant to gather internal measurements (during DDSDomainParticipant creation) that are required for the Auto Throttle feature. This allows DataWriters belonging to this DDSDomainParticipant to use the Auto Throttle feature.

The turbo_mode adjusts the batch max_data_bytes based on how frequently the DDSDataWriter writes data.

Data_writer.auto_throttle enables automatic throttling in the DDSDataWriter so it can automatically adjust the writing rate and the send window size; this minimizes the need for repairing DDS samples and improves latency.

◆ DDS_SNIPPET_TRANSPORT_TCP_LAN_CLIENT

const char* const DDS_SNIPPET_TRANSPORT_TCP_LAN_CLIENT
extern

QoS Snippet that configures a TCP LAN Client over DDS.

This QoS Snippet sets all the mandatory properties; however the final QoS Profile requires additional configuration.

The values of the initial_peers and the property dds.transport.TCPv4.tcp1.server_bind_port are incorrect (just sample strings). Therefore, they must be modified:

  • initial_peers: should point to the remote client IP and port.
  • server_bind_port: is the port this application will be using.

This modification should be done in the QoS Profile that will be used to create the DDSEntity. These new values will overwrite the current invalid values.

◆ DDS_SNIPPET_TRANSPORT_TCP_WAN_SYMMETRIC_CLIENT

const char* const DDS_SNIPPET_TRANSPORT_TCP_WAN_SYMMETRIC_CLIENT
extern

QoS Snippet that configures a symmetric WAN TCP Client over DDS.

This QoS Snippet sets all the mandatory properties; however the final QoS Profile requires additional configuration.

The values of the properties dds.transport.TCPv4.tcp1.public_address and dds.transport.TCPv4.tcp1.server_bind_port are incorrect (just sample strings). Also the initial_peers information is not correct. Therefore, the following must be modified:

  • initial_peers: should point to the remote client IP and port.
  • public_address: public IP address where this application can be reached.
  • server_bind_port: port this application will be using.

This modification should be done in the QoS Profile that will be used to create the DDSEntity. These new values will overwrite the current invalid values.

The values of the properties dds.transport.TCPv4.tcp1.public_address and dds.transport.TCPv4.tcp1.server_bind_port are incorrect (just sample strings). Therefore, they must be modified to the corresponding public_address and port_number. This modification should be done in the QoS Profile that will be used to create the DDSEntity. These new values will overwrite the current invalid values.

◆ DDS_SNIPPET_TRANSPORT_UDP_AVOID_IP_FRAGMENTATION

const char* const DDS_SNIPPET_TRANSPORT_UDP_AVOID_IP_FRAGMENTATION
extern

QoS Snippet that configures RTI Connext and the UDP built-in transports (UDPv4, UDPv6, UDPv4_WAN) to avoid IP fragmentation.

For WAN communications and, in general, for communications in third party networks, it is not a good idea to rely on IP fragmentation. IP fragmentation causes significant issues in UDP, where there is no integrated support for a path MTU (maximum transmission unit) discovery protocol as there is in TCP.

This snippet provides a way to avoid IP fragmentation in Connext applications using the built-in UDP transports. Instead, Connext will be responsible for fragmentation, which is done at the RTPS level.

Among other changes, this configuration changes the transport MTU (message_size_max) to be 1400 bytes. Notice that this change will affect other transports such as SHMEM since Connext chooses the minimum transport MTU across all enabled transports to determine the maximum size of outgoing RTPS messages.

◆ DDS_SNIPPET_COMPATIBILITY_CONNEXT_MICRO_VERSION_2_4_3

const char* const DDS_SNIPPET_COMPATIBILITY_CONNEXT_MICRO_VERSION_2_4_3
extern

QoS Snippet that configures sets LIVELINESS QoS to be compatible with RTI Connext Micro 2.4.3.

QoS Snippet that sets the DDS_DataReaderQos and DDS_DataWriterQos DDS_LivelinessQosPolicyKind to DDS_MANUAL_BY_TOPIC_LIVELINESS_QOS It also disables the built-in shared memory transport.

Modified QoS Parameters:

RTI Connext Micro versions 2.4.3 and earlier only supported DDS_MANUAL_BY_TOPIC_LIVELINESS_QOS DDS_LivelinessQosPolicyKind. In order to be compatible with RTI Connext Micro 2.4.3, the DDSDataReader and DDSDataWriter must have their DDS_LivelinessQosPolicyKind changed to this value because the default kind in RTI Connext is DDS_AUTOMATIC_LIVELINESS_QOS.
